System and method for cloud security monitoring

ABSTRACT

The invention relates to a computer-implemented system for security monitoring of Member accounts in a cloud environment. The Member accounts are provided as instances of cloud services in one or more monitored clouds by one or more cloud service providers. The system is programmed to automatically deploy software agents to the Member accounts. The software agents are configured to monitor activities in the Member accounts and to push security and operations data to a SIEM platform. The security and operations data may comprise alerts and activity logs for the Member accounts, public internet protocol (IP) addresses used by the Member accounts, and identifying information for individuals and information technology (IT) assets associated with the Member accounts. The system includes a user interface to define customized alerts based on the security and operations data, and the system generates and sends the customized alerts to a system administrator or security analyst.

FIELD OF THE INVENTION

The present invention relates generally to a system and method for cloud security monitoring.

BACKGROUND

Cloud services have become targets for threat actors and insider threats who seek unauthorized access to sensitive data stored in the cloud. Conventional cloud services have logs that record instances of attempted access and other actions. However, threat actors may attempt to delete such logs, and in some cases, even administrators may tamper with or delete such logs for illegitimate purposes. Additionally, regulatory compliance frameworks may dictate requirements for log retention and immutable properties that cloud security monitoring enforces. Another challenge that business entities may face in securing their data is the utilization of multiple instances of multiple cloud services, such as Amazon Web Services, Microsoft Azure, Google Cloud Platform, or others. It is desirable that such a business entity be able to collect logs from various cloud services to allow its information technology (IT) and security teams the ability to perform threat analysis, incident response, vulnerability assessment, operational monitoring, application monitoring, cloud inventory, or near real-time compliance validation on monitored cloud environments from a central “pane of glass.” However, conventional security monitoring of cloud services may typically involve labor-intensive deployment procedures and inconsistent processes across cloud providers, such as manual implementation of various configurations to deploy security monitoring measures in the cloud. This type of manual deployment may lead to drift from needed logging configurations by requiring the administration team to account for the logging configurations on resources deployed.

Exemplary embodiments of the invention provide systems and methods to overcome these and other disadvantages of known systems and methods.

SUMMARY

Systems and methods for performing cloud security monitoring (CSM) are described herein. The monitored cloud may be a commercial or government partition that provides cloud services such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or another cloud service. A Security Incident and Event Management (SIEM) platform may be provided, for example, in another cloud instance for the purposes of security monitoring, which is separate from the monitored cloud. The STEM platform can act as the final aggregation and archive location for alerts and logs generated in any of the cloud service providers. It can also provide the platform that enables analysts to perform analytics, reporting, and alerting across the cloud environments.

According to one embodiment, the cloud security monitoring system may include automated collection or scraping of assigned public internet protocol (IP) addresses from monitored clouds for the purpose of updating the vulnerability assessment platform on a periodic basis. This may be accomplished via the use of dedicated scripts that are designed to interrogate the cloud providers' API endpoint(s) with specific queries that are constructed to extract the needed public IP information (public IPs, ports, other configurations), parse the output from the API endpoint(s), format the data, and forward the final output to various locations. The scripts may be run from the cloud service provider's serverless services (e.g., Azure Functions, AWS Lambda (k), etc.) to eliminate the need to maintain virtual servers and reduce downtimes caused by virtual server operational interruptions or misconfigurations. Frequent collection, updating, and analysis of the public IP addresses allows the CSM system to alert IT teams to configurations that elevate the risk of an asset being accessed by unauthorized entities and used for nefarious activities. Frequently, threat actors or malicious software utilize the public IP interfaces assigned to IT assets to pivot onto the network, access and exfiltrate corporate data, or perform attacks against the IT infrastructure of other organizations. By performing an analysis of the perimeter (public IP addresses in use, ports exposed to the Internet, and services sending/receiving network communications) of each environment, the attack surface may be understood and appropriate actions taken to accept the risk or remediate the configuration that could be leveraged against an organization by threat actors. The CSM system may also be configured to remediate such configurations by taking action to remove or adjust the firewall rules that allow network communication to that public IP, port, or service. This may be accomplished by sets of scripts used by serverless technologies. These scripts have the intelligence built into the automation to interact with the management plane of the cloud provider via its API endpoint to make the adjustments to the firewall rules that are applied to the public interface assigned to the asset. Additionally, the same automation may be used by the anomaly detection service to shut down a network communication path that generated an alert noting an attack against the resource by threat actors.

The cloud security monitoring system and method may include fully automated deployment of an entire cloud security monitoring stack in the monitored cloud. According to one embodiment, the cloud security monitoring system and method may include automated deployment of CSM code to all regions servicing the business, and automated deployment of the CSM code to one or more additional regions based on usage. This is accomplished through the use of templates (e.g., Azure Resource Manager templates, AWS Cloud formation templates, etc.) and deployment scripts (e.g., PowerShell, Bash, etc.) to automate the needed configuration and resource deployments that support CSM. Templates are used to deploy the infrastructure that supports the flow of log data to the STEM platform. The scripts are used to interact with the management plane's API endpoint and allow for configurations (e.g., activation of logging configurations on existing resources, creation of service accounts, enablement and configuring of specific services not supported in templates) across the cloud environment to be adjusted in support of CSM. The CSM code may be configured to automatically push cloud logs generated in the monitored cloud (e.g., AWS or Azure) to the Security Incident and Event Management (SIEM) platform (e.g., Splunk). Collection of the cloud logs in the SIEM platform allows the system administrator to create custom queries and alerts, which may provide near real-time visibility into the operation of all cloud services utilized by the business entity (e.g., AWS, Azure, Google Cloud Platform). The cloud security monitoring system and method may also include an automated notification to alert a system administrator when a log fails to be delivered to the STEM platform. In the event the automation is processing events to be sent to the SIEM platform and an error is encountered in the transmission of the log to the STEM, the automation has the capability of noting the error in its processing logs and archiving the cloud logs that failed transmission in the cloud provider's storage solution (e.g., Azure storage blob, AWS S3 bucket, etc.). When new cloud logs that failed transmission are deposited into the storage structure, automation is triggered with the purpose of notifying defined contacts of the failure. The administrator that received the failure notification may retrieve the automations processing logs to determine the root cause of the transmission failure for remediation. Additionally, the administrator may collect the logs which failed delivery to the SIEM platform from the storage structure and re-inject them into the log streams via a set of pre-defined commands that interact with the cloud providers' API endpoint(s), thus allowing for failed log delivery to the SIEM platform once the failure root cause has been remediated. This allows for no loss of log data in the event of failure.

According to another embodiment, the cloud security monitoring system and method may include automatic adjustment of throughput between a Logging account, which may reside in the monitored cloud, and the STEM platform, to address service thresholds. To accomplish this, the automation monitors the processing logs of the service (e.g., AWS Kinesis FireHose) and when an event is encountered with an entry stating, for example, WriteProvisionedThroughputExceeded the automation may increment the number of shards assigned to the AWS Kinesis FireHose output stream. Adjusting the number of shards assigned to each stream allows the throughput to be expanded or contracted on a per log type basis.

The cloud security monitoring system and method may include other advantageous features. For example, the CSM system and method may provide automatic configuration of a list of available monitoring services that is customized based on the particular use case of the cloud service. The CSM system and method may include automatic remediation, automatic healing, or automatic fixing of misconfigured resources that caused cloud security monitoring to fail. In support of this feature, CSM can utilize the cloud provider's compliance engine (e.g., Azure Policy, AWS Config, GCP Forseti, etc.). A set of CSM compliance (custom or cloud provider managed) rules can be deployed with a template. These rules are used by the compliance engine to assess the configuration of the resource and determine if the resource has the necessary configurations to support log collection by CSM. In the event that the resource is non-compliant with CSM configurations, automation (e.g., Azure Policy DeployIfNotExists, AWS Lambda (λ)) is triggered that is designed to remediate the configuration and bring the resource into compliance with CSM configurations. In AWS, Lambda (λ) functions are scripted to interact with the API endpoint(s) that service the non-compliant resource. Commands are constructed and sent to the API endpoint(s) by the automation to bring the non-compliant resource into compliance with CSM configurations. In Azure, Azure Policy is leveraged with a DeployIfNotExists setting that allows the compliance engine to make the needed configuration changes based on the policy Rule Definition used to assess the resource. The compliance of the CSM configurations across resources is reported to the SIEM platform for alerting, reporting, and auditing.

The CSM system and method may include a feature that allows for identity and asset scrapping functionality that collects inventory and configuration information on all identities and resources (e.g., servers, services, storage structures, databases, etc.) provisioned within the cloud environment. This information, when combined with the cloud logs in the Security Incident and Event Management (STEM) platform, allows the CSM system to provide a more comprehensive and insightful analysis of the use of the cloud services. Additionally, the inventory of identities and assets may be used to create or populate a Configuration Management Database (CMDB) for cloud environments.

The CSM systems and methods may allow a business entity to reliably perform cloud security monitoring in multi-tenant environments and allows for a single pane of glass across the cloud estate. Aggregating the cloud log data, inventory, and alerts from various tenants in separate cloud providers allows for a central analysis portal to perform effective monitoring without inducing fatigue; from multiple logins, complexity of determining source environment, multiple identities, etc. Additionally, it can reduce time of response to alerts by providing a single place to receive alerts from multiple tenants and across multiple cloud service providers. In this embodiment, the monitoring analyst is not required to log into each environment, review the alerts, and move on to the next environment. Removing this manual review both reduces the time of response and can eliminate failure to respond as it eliminates confusion caused by alerting mechanisms that don't track status and assigned resources (e.g., email based alerts, instant messaging based alerts, etc.). In CSM, the alerts are collected by means of automation that is designed to interact with the API endpoint that services the anomaly detection technology. The automation performs a series of queries targeting the API endpoint and extracts any newly generated alerts. This collection method is extended to also capture alerts generated by other STEM software. Extending CSM to also collect alerts being generated by member SIEMs allows environment administrators the flexibility to use STEM technologies of their own choosing, while providing the needed visibility into their environments.

The Cloud Security Monitoring model puts into place automation that assesses the logging configurations of resources deployed within the account. This automation can be used to enable logging on resources that were deployed without the needed logging capabilities enabled. Intelligence can be built into the automation that allows it to determine the location where each resource type needs to send their logs and is able to apply this knowledge to the logging configuration of the resource. Typical solutions also require access to the Member accounts in the form of a service account to allow the monitoring solution to “pull” logs from the environment. The Cloud Security Monitoring (CSM) solution provides the ability for a “push” architecture that allows for a “zero access model” to monitor the Member account. Having this capability allows for scalability, performance increases, and reduction of attack surface over traditional “pull” methodologies.

The Cloud Security Monitoring model makes use of an aggregation environment before logs are pushed to the STEM. This allows the automation to continue servicing other integrated environments in the event that a compromise of a workload in a monitored environment occurs. Additionally, this allows for a central place to update the automation with new iterations of CSM source code. To accomplish this, CSM makes use of cross environment policies assigned to the identities. In Azure, the identity is given the appropriate permissions at the subscription level and this allows all resources to inherit and allow retrieval of log data where defined in the permissions. In AWS, roles are defined to allow the automation to retrieve the appropriate log data or allow services to interconnect with each other (e.g., AWS CloudWatch to AWS Kinesis Data Streams). This is handled via the policies assigned to the roles. The credentials in use are managed by the CSP and are rotated for each session.

These and other advantages will be described more fully in the detailed description below.

DETAILED DESCRIPTION

Exemplary embodiments of the invention will be described in order to illustrate various features of the invention. The embodiments described herein are not intended to be limiting as to the scope of the invention, but rather are intended to provide examples of the components, use, and operation of the invention. For example, although some embodiments may be described in which the monitored cloud comprises an Amazon Webs Services (AWS) cloud or Microsoft Azure cloud, the scope of the invention is not limited to these two types of clouds. Moreover, although some embodiments may be described in which the security incident and event management platform is provided by a Splunk Cloud, the scope of the invention is not limited to Splunk Cloud.

Public IP Bucket. According to one embodiment, the CSM system includes a public IP bucket comprising an electronic storage area that maintains a list of publicly accessible IP addresses. When a business entity configures or creates a service in the cloud, the implementation of the service may automatically generate an exposed public IP addresses that can be exploited by threat actors who are monitoring the cloud service for access points. According to an embodiment, the public IP bucket of the CSM system is configured to store IP addresses that are exposed to the Internet. The CSM system may be configured to automatically update the public IP bucket when new IP addresses are created, to update the vulnerability management platform, to update the inventory of public IP addresses in the security incident and event management (STEM) platform, and to automatically notify the relevant system administrators or security analysts of new public IP addresses. CSM monitors the API logs that are generated by the cloud provider. When specific API calls are made (e.g., API calls to AWS RunInstance or AssociateAddress, in Azure MICROSOFT.NETWORK/PUBLICIPADDRESSES/WRITE, etc.), CSM has the capability of triggering automation to perform various tasks, including but not limited to notifying administrators, updating inventories, scanning with a vulnerability management platform, removing or preventing network communication with the interface, and updating vulnerability management platform groups for scheduled scanning. The CSM system may also allow a business entity to prevent threat actors or other unauthorized users from using an IP address that has been logged in the public IP bucket by reporting on system exposure or dangerous configurations, or taking action to close the network communication path by eliminating or adjusting security group rules. In one embodiment, the CSM system may be used to automatically shut down the use of an IP address in the event the CSM system detects an anomaly or unauthorized user attempting to use such address. In addition, a copy of each log entry corresponding to each attempted access using an IP address in the public IP bucket may be stored within the account for review by a local cloud administrator. These functionalities enable an administrator of the CSM system to reduce or prevent unauthorized access to the cloud through public IP addresses by providing real time or near real time notice of public IP address creation and can be used for automatic shut down in the event of unauthorized access.

The cloud security monitoring system and method may include automated scraping of assigned public IP addresses from monitored clouds for vulnerability scanning on a periodic basis. The period for conducting the scraping may be configured in the CSM system to near real-time or less frequent, e.g., every 15 seconds or every 60 minutes. The frequent scraping can enhance security by reducing the time between creation of a new public IP address in the monitored cloud, and the time that the CSM system begins monitoring use of the new public IP address. CSM monitors the API logs that are generated by the cloud provider. When specific API calls are made, e.g., API calls to AWS RunInstance or AssociateAddress, in Azure MICROSOFT.NETWORK/PUBLICIPADDRESSES/WRITE, etc., CSM has the capability of triggering automation to perform various tasks, including but not limited to notifying administrators, updating inventories, scanning with a vulnerability management platform, removing or preventing network communication with the interface, and updating vulnerability management platform groups for scheduled scanning. The CSM method may also include automated updating of the assigned public IP addresses scraped from the monitored clouds in the vulnerability management platform.

Automated Deployment of CSM Code; Push Logs to Splunk. According to one embodiment, the cloud security monitoring system and method may include fully automated deployment of an entire cloud security monitoring stack in the monitored cloud. The CSM system and method may include automated deployment of CSM code to select or all regions served by the business, and automated deployment of the CSM code to one or more additional regions based on usage. This is accomplished via CSM monitoring the API interactions that are occurring within the cloud infrastructure. When API calls are made that originate from regions other than a region that CSM is monitoring, the system may trigger the deployment of code to additional regions where resources have been deployed to support dynamic visibility across CSP regions. A multitude of configurations can allow this to happen, for example, a template residing within a storage structure can be referenced that allows for the deployment of CSM to additional regions analogous to the initial deployment of CSM. The CSM application may comprise of software agents that can be deployed to virtual servers residing in multiple locations in the monitored clouds (e.g., multiple instances of AWS, Azure, and GCP) through the use of automation.

The CSM code may be configured to automatically push cloud alerts and logs generated in the monitored cloud to the security incident and event management (STEM) platform (e.g., Splunk Cloud). Collection of the environment's logs in the STEM platform allows the system administrator to create custom queries and alerts, which may provide real time visibility into the operation of all instances of all cloud services utilized by the business entity. The cloud security monitoring system and method may also include an automated notification to alert a system administrator when a log fails to be delivered to the STEM platform. During log processing, the CSM system in Azure is designed to process logs and provide the security incident and event management platform with the necessary metadata to be able to classify and properly store the cloud log information that is being ingested. The automation is able to do this by monitoring the log provider field within each log entry or by monitoring the CSM infrastructure that is extracting and sending the data to the security incident and event management platform (STEM). While monitoring these fields within the cloud logs, CSM may determine the source of the log and classify it for the SIEM. The automation first classifies the cloud log, retrieves the secret that is needed to authenticate and authorize the log to be ingested into the STEM, builds header information to be consumed by the SIEM aggregation technology, then combines the segregated bits of information to allow for the sending and ingestion of the cloud logs into the SIEM. In AWS, this is accomplished by leveraging a number of mechanisms; cloud log data is first aggregated in the native AWS service CloudWatch. Automation has been designed to place the correct log destination that allows for a CloudWatch Subscription Filter to be placed on the log group. Each log type receives its own log group/subscription filter and allows for the sending of logs to an AWS Logging account. Upon receiving the log, the AWS Logging account forwards the cloud log to the AWS Kinesis Data Streams service. This input mechanism is used to transfer the data from AWS CloudWatch log destinations to AWS Kinesis FireHose service for output to the STEM. As AWS Kinesis Data Stream takes data as an input, it forwards the data to the AWS Kinesis FireHose to be decompressed, possibly enriched with other data that is available within the environment, and sent to the SIEM.

Auto Configuration. According to one embodiment, the CSM system includes automatic remediation of logging configurations based on the needs defined by the consumers of the CSM cloud data. Many resources that are deployed do not have logging enabled. To facilitate the visibility of logging requirements, CSM is capable of altering the logging configuration of resources deployed within the environment. The automation is capable of leveraging the API endpoint(s) that controls the configuration of the resource. CSM issues a series of API commands that allow the configurations of targeted resources to be changed. An example of this includes an administrator deploying a load balancer to route Internet traffic for the environment's servers. CSM will take note of the newly deployed resource, evaluate its logging or compliance configuration against the defined standards, and take action by applying the needed configurations if those configurations are not in place. This allows the continued enablement of visibility with near real-time automated assessments of all resources that are in-scope for CSM to monitor.

Auto Healing. In one embodiment, cloud security monitoring may include alteration of the current configuration, automatic remediation, automatic healing, or automatic fixing of misconfigured resources that cause cloud security monitoring to fail. For example, if the monitored cloud comprises of an AWS cloud instance or deployed cloud resource, custom configuration rules and CSP-provided configuration rules may be implemented to determine whether remediation is necessary. Upon determining that the resource's configuration varies from the standard required by CSM, a series of automated corrective actions are performed to adjust the configuration to return the resource to its desired configuration and allow for visibility into the operations of the resource.

Integration of AWS functions with Lambda (λ). According to another aspect of the invention, the CSM system is able to integrate disparate and segmented cloud service providers (CSP) offerings. This is accomplished through the use of CSP serverless offerings. Custom code leverages the CSP's API endpoint(s) to make any integration possible. The serverless offerings allow for the interaction, connection, or consumption of data capable of being utilized by the CSM system. This includes, but is not limited to, collection of (system or stored) data, actions taken against the cloud environment or resources, enrichment of any data point received by CSM, or any custom logic needed by the consumer of CSM for any need (e.g., forwarding, analysis, enrichment, reporting, action, etc.). For example, load balancers are typically deployed with a configuration that does not provide visibility that supports information technology teams with understanding of how the resource operates, the data it receives, the network communications that it is forwarding, or the clients that it is servicing. This may hinder the ability for the resource to be understood from an operational or security perspective. Access logs of this resource are sought to perform analysis such as user interactions, operating system interactions, browser user agents, IP address interactions, data usage, etc. To support the needed visibility and lack of direct integration, CSM may pair varying services together that as a whole allow for the transmission of cloud data to the necessary system of choice (e.g., vulnerability management platform, security incident and event management platform, security orchestration and automated response platform, security incident management platform, ticketing system, inventory system, etc.).

ID and Asset Scraping. According to another embodiment, the CSM system and method may include an identity and asset scraper functionality that collects information on users, service accounts, and cloud resources of the business entity. The cloud service providers (CSP) API endpoint(s) is leveraged to query for the needed inventory information. This data, when combined with the cloud logs in the security incident and event management (SIEM) platform, allows the CSM system to provide a more comprehensive and insightful analysis of the use of the cloud services by allowing: an understanding of cloud resources, correlation of logs against an inventory of assets, remediation based on asset or identity information, precise identification of assets or identities within alerts, etc.

Self-Monitoring. According to another embodiment, the solution is designed to monitor the security posture of its own components by monitoring IaaS and PaaS offerings in multiple cloud service provider platforms. CSM itself makes use of PaaS offerings to move and transform log records on their journey to the final destination. The same mechanisms (e.g., audit logs, anomaly detection, configuration monitoring, etc.) that are used to monitor a Member account, are applied to the solutions support infrastructure. This allows a security team to monitor the health of CSM and detect anomalous behavior by its varying components.

SIEM of SIEMs. According to another embodiment, the CSM solution is designed to be the SIEM of SIEMs. This allows environment administrators the flexibility to use the technology of their own choosing for log analysis, while still allowing CSM to provide the required visibility into the alerts generated by any STEM technology, including those deployed natively by the cloud providers. The method of capture makes use of API endpoints assigned to service the monitored native cloud provider STEM. Specifically, the method of security alert collection for a vendor or cloud provider STEM is performed by: (1) requesting an access token from an Identity provider (IdP), (2) using the access token to request a bearer token, and (3) using the bearer token to query workspace that STEM is using for any alerts generated in a configurable time period. This flexibility allows the CSM solution to be the top tier STEM in a hierarchical topology of STEM deployments.

Port Identification. According to another embodiment, the CSM system provides monitoring of selected ports associated with an IP address. In general, an IP address may have thousands of ports associated with it. In addition, certain cloud providers such as AWS may monitor and prevent automated crawling of ports by third-party software agents that interact with all ports associated with an IP address. In order to facilitate the monitoring of selected ports without using a crawling agent, the CSM system may be programmed to detect, store and retrieve the ports that are used in connection with an IP address. This is done by querying the varying cloud service provider (CSP) API endpoint(s) to determine the exact port information that is needed. Having this information allows the CSM system to monitor the active ports without using a crawling agent to monitor all ports, which would normally be prevented by AWS or other intelligent response capabilities offered by default to CSP customers. The CSM system may also provide detection of crawling of ports used by threat actors and take corrective actions to remediate it (e.g. by temporarily shutting affected ports down, preventing access from specific IP addresses etc.).

Throughput Adjustment. In an embodiment, cloud security monitoring may include automatic adjustment of throughput between the Logging account, which may reside in the monitored cloud, such as AWS or Azure cloud, and the STEM platform, such as Splunk Cloud, to address service thresholds. To accomplish this, the automation monitors the processing of logs of the service (AWS Kinesis FireHose) and when an event is encountered with an entry stating WriteProvisionedThroughputExceeded the automation increments the number of shards assigned to the AWS Kinesis FireHose output stream. Adjusting the number of shards assigned to each stream allows for the throughput to be expanded or contracted on a per log type basis. When the cloud log does not contain the aforementioned entry for a configurable amount of time, the automation may decrement the number of shards assigned to each stream. Doing so reduces the costs of maintaining multiple shards that are not being used to process cloud data.

Auto-updating. The CSM system that runs in AWS has the ability to self-update the CSM code that is running within the cloud environment. The feature leverages a series of serverless functions and Cl/CD pipelines that allow CSM to monitor a specific file that is held within a storage structure accessible by CSM. The automation monitors a file on a configurable interval for changes to the MD5 hash value which indicates that a new version is available. The automation then makes a copy of the needed deployment templates, triggers the necessary deployment mechanisms (e.g., AWS CloudFormation), and monitors for the status of the deployment. Additional automation may be triggered to identify issues and failures encountered during deployment.

Agent deployment. In another embodiment, CSM has the capability of deploying security agents to servers with automation. This is accomplished through native services in each CSP (e.g., Azure custom script extensions, AWS System manager automation documents, etc.). Each Member account that has integrated CSM with the environment is made available the automation documents to:

-   -   1. Test if the agent is installed,     -   2. If the agent is not installed and running, the code         -   2.1. Gathers the security agent installation package from             the appropriate storage structure,         -   2.2. Installs the agent using the pre-configured             installation commands, and         -   2.3. Reports back to the administrator any successes or             failures.             This automation applies to various operating systems (e.g.             Linux, Windows).

The CSM system that runs in AWS also has the ability to rotate all authentication tokens in use by the Logging account across all regions. To accomplish this, the CSM system monitors for changes to the AWS System Manager parameter store that contains the security incident and event management (SIEM) platform authentication tokens. When changes to the AWS System Manager parameter store are noted by CSM, automation (e.g., AWS Lambda) is triggered that collects the values of the tokens, identifies the AWS Kinesis FireHose stream that should use the token, and updates the value used by the AWS Kinesis FireHose stream. Upon updating this token, the stream begins to utilize the updated token. This provides IT teams the ability to update authentication tokens in one place, and have those tokens propagate across corresponding logging output mechanisms.

Referring now to the drawings, FIG. 1 illustrates an example of a cloud security monitoring system with multiple Member accounts in AWS cloud. According to one embodiment, for each Member account, such as Member Account 1, a Logging account and a Security account are provided. The Member account may include a public IP scraper to perform automated scraping of assigned public IP addresses from monitored clouds. Automated updating of the assigned public IP addresses scraped from the monitored clouds may be performed in a vulnerability management platform, such as Qualys. All scrapping and updating of the information is accomplished over the platforms API. Vulnerability scanning may be performed on a periodic basis at a desired frequency, upon the occurrence of certain events, or on demand by a system administrator, for example.

According to one embodiment, built-in automated updating of HTTP Event Collector (HEC) tokens used to authenticate the logs in Splunk Cloud may be provided by the HEC update Lambda (λ) function in the Logging account. Notifications to alert administrators of log failures may be delivered by the Logging account to Splunk Cloud. Alert notifications may be processed and presented in a format readable by humans. Automatic adjustment of throughput between the Logging account and Splunk Cloud may be provided to address and satisfy a service threshold. Automated deployment of CSM code to all existing regions, and into additional regions based on usage, may be provided.

FIG. 2 illustrates an example of cloud security monitoring in AWS cloud having a Member account, a Security account, and a Logging account with a log flow path to Splunk Cloud. The Member account may include CloudWatch LogGroups and the Security account may include CloudWatch LogGroups and Security Hub (Master). The Logging account may provide a log flow path to Splunk Cloud. The Logging account is provided between the monitored cloud and Splunk Cloud to prevent administrators or hackers from tampering with or deleting the logs. In one embodiment, automated updating of HEC tokens used for authentication in Splunk Cloud may include automated rotation of HEC tokens, which may be performed by the HEC update Lambda (λ) function in the Logging account.

FIG. 3 illustrates an example of cloud security monitoring in AWS cloud having a Member account, a Security account, and a Logging account, where the Security account includes a public IP bucket and an AWS S3 assets bucket. Endpoint agents may be staged in the S3 assets bucket in the Security account and automatically deployed to servers in the Member accounts. A public IP scraper, which may be a Lambda (λ) function, may be provided in the Member account. Automated updating of the assigned public IP addresses scraped from monitored clouds may be provided.

FIG. 4 illustrates an example of cloud security monitoring in AWS cloud having a Member account which includes a public IP scraper and an identities/assets scraper. In one embodiment, CSM code implemented through a Lambda (λ) function may be provided to extract log messages from the S3 buckets and to push them to CloudWatch, such that a copy of each log entry is maintained for a local cloud administrator. The public IP scraper may be programmed to automatically gather needed information from each service with public IP addresses assigned, regardless of whether those IP addresses are exposed to the internet or not.

According to one embodiment, all identities of individuals and IT assets or resources may be automatically collected within a monitored cloud by the identities/assets scraper and may be automatically inventoried. In addition, cloud misconfiguration assessments generated by the AWS Trusted Advisor in the Member account may be automatically gathered. Automatic remediation, automatic healing or automatic fixing of misconfigured resources that cause CSM to fail may be provided, which will be described in further detail with respect to FIG. 6.

FIG. 5 illustrates an example of the deployment of the AWS Config service. AWS Config provides resource information that CSM consumes. In order to properly deploy the AWS Config service, a series of steps that are dependent upon information from previous steps are needed. In order to accomplish a successful deployment, CSM follows the logic described in FIG. 5. The automation is designed to intelligently determine the needed configurations to ensure a successful deployment. Information that is gathered includes analysis of the region that is designated as the “master region” or the main operating region where AWS global resources are deployed, if a previous AWS Config service instance is deployed, and reports back to the administrator any issues that are encountered during the deployment. Upon successful deployment of the service, a number of managed and customized rule sets are deployed to accomplish any monitoring needs that span security, compliance, inventory, operational, or other needs.

FIG. 6 illustrates an example of a process for cloud security monitoring in AWS cloud with automatic remediation, automatic healing or automatic fixing of misconfigured resources.

FIG. 18 illustrates an example of cloud security monitoring in Azure cloud with Azure automation and runbooks. According to one embodiment, an Azure Automation Runbook (azureinventory_runbook) may be provided to pull resource-level details from Azure Graph as well as information on Azure Security Center configuration, policy assignments, role assignments, and current user list from Azure AD (Active Directory). This runbook may be set to run daily, or in other predetermined time intervals, to push a new set of inventory/configuration on each execution.

According to one embodiment, an enable Network Watcher runbook (enableNetworkWatcher_runbook) may be provided to monitor the NSGs that are currently deployed and to enable Network Watcher in any region in which it needs to be deployed. According to one example, this runbook may be set to run every hour, or in other predetermined time intervals. An enable NSG flow runbook (enableNSGFlow_runbook) may be provided to validate each NSG for flow log settings and to correct those settings if needed. This runbook may point NSG flow logs to the storage accounts that are managed by the CSM model. This runbook may be set to run every hour, or in other predetermined time intervals.

In another embodiment, the CSM solution allows for Configuration Monitoring of the cloud environments. This is done in several ways:

-   -   1. For real time alerting of configuration changes or         misconfigurations being applied to resources, CSM can make use         of the audit logs that are being collected. This log source         contains the configuration information that is being applied to         the resource (existing or new resource). Alerts can be setup in         the STEM to notify security analysts when a resource is         improperly configured.     -   2. Using the native cloud service provider's compliance engines,         a number of “rules” have been put in place that allow for a         reaction when a misconfiguration is identified. The “rules”         contain information that allow for the misconfiguration         identification. Once identified, automation is triggered that         interacts with the resources API endpoint and a configuration         change API call is made. This changes the misconfiguration on         the resource to be in compliance with the aforementioned         “rules.”     -   3. Third party cloud configuration monitoring software can also         be integrated. The identity and permissions assigned to the         identity is used by the third-party software and is deployed as         part of the CSM solution. This identity is then used by the         third party software to analyze the management plane of each         environment. This software then alerts when rules are triggered         by misconfiguration analysis.

An enable SA (Storage Account) logging runbook (enableSALogging_runbook) may be provided to monitor all storage accounts and to enable logging if needed. This runbook may be set to run every hour, or in other predetermined time intervals. A centralized SA logging runbook (centralizeSALogging_runbook) may be provided to copy new storage logs from the storage log container on every storage account to a centrally managed storage account that is then used to move the logs to Splunk Cloud. In one embodiment, this runbook may be set to run every hour, or in other predetermined time intervals.
